Abstract (en)
Process for modifying tacky surfaces, e.g., tacky layer on a photograph or other photochemically produced record such as a multilayer surprint proof, which comprises applying an admixture of particulate material and carrier particles and removing the excess particulate material and carrier particles. Prior to applying the admixture onto the surface of the surprint proof the tacky outer layer can be exposed through a halftone screen tint. The ratio of average particle diameter of the carrier particles to average particle diameter of the particulate material is greater than 2 and the weight ratio of particulate material to carrier particles is less than 1. The degree of surface modification, e.g., light reflectivity, etc., can be controlled by the process.
